Project planning, powered by probabilistic reasoning

Bayes.ai combines constraint solving with Monte Carlo simulation to give you realistic schedules — not wishful thinking.

Built for realistic planning

Four capabilities that work together to produce schedules you can actually trust.

Scenario Analysis

Generate a graph topology that models alternative scenarios; compare outcomes side by side.

Constraint Solving

Define relationships between tasks, costs, and resources. The solver finds feasible schedules automatically.

Monte Carlo Simulation

See P10/P50/P90 completion estimates from thousands of probabilistic scenarios.

Bayesian Learning

Record actual durations as tasks complete. Risk profiles update automatically, so re-running the plan produces schedules grounded in real performance — not guesswork. This is the "Bayes" in Bayes.ai.

Your data stays yours

Privacy by design. No tracking, no data harvesting, no surprises.

On-device storage

Project data lives in your browser by default. Nothing is uploaded to our servers, unless you share a schedule or choose to save your plan to our cloud storage service.

Stripe-managed accounts

Billing and account management handled directly by Stripe. We never see your payment details.

AI without retention

Paid users can upload files to generate plans with AI. Bayes.ai does not store uploaded files or their contents.

Generate plans from what you already have

Upload project briefs, scope documents, or spreadsheets. AI extracts tasks, dependencies, and estimates — then the files are discarded.
